Those 3 silver coins have an owl each on reverse. Obverses could be Athena. They are offered to me for sale and sent by iPhone. Are they authentic ? How much shall I pay ? Thank you.
Never know dude. I got an ancient roman coin in a USD lot once, and according to the local coin shop, it was likely authentic!
There is a bit of a famous story in the trading card community that goes that there was a man who had found a killer deal on the now infamous card "Black Lotus" (Roughly $20,000-$40,000 USD depending). When he had gotten to the gas station that they had agreed to meet at, he was robbed at gun point. After giving the man the cash he was going to spend on the card, he was shot, and the thief ran away. Long story short: Don't trust people you don't know, they WILL SCREW YOU OVER!
I also think you should pass the offer. The owl design is quite suspicious. Eyes way too big, and the legs dangling?
